How do you disable MouseOver effects on a Button in WPF? - wpf

Question

I'm trying to disable the MouseOver effect on buttons, or at least change the colour of it, in WPF.
I'm using the following style:
<Style x:Key="Borderless" TargetType="{x:Type Button}">
<Setter Property="OverridesDefaultStyle" Value="True"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Button Background="{TemplateBinding Control.Background}"
Focusable="False">
<ContentPresenter
Margin="{TemplateBinding Control.Padding}"
HorizontalAlignment="{TemplateBinding Control.HorizontalContentAlignment}"
VerticalAlignment="{TemplateBinding Control.VerticalContentAlignment}"
SnapsToDevicePixels="{TemplateBinding UIElement.SnapsToDevicePixels}"
ContentTemplate="{TemplateBinding ContentControl.ContentTemplate}"
RecognizesAccessKey="True"
Content="{TemplateBinding ContentControl.Content}" />
</Button>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
in Window.Resources, which I thought would override all the default behaviours. But it doesn't.
Any suggestions?

Look what your control template boils down to:
<ControlTemplate TargetType="{x:Type Button}">
<Button>
<ContentPresenter/>
</Button>
</ControlTemplate>
You're saying, "I want to replace the look of my button with... a button." The usage of the ControlTemplate is to replace the visual tree of a control. So you are replacing the visual tree of the existing button with another button. If you want to start a button from scratch, try using the SimpleStyles button:
<Style TargetType="{x:Type Button}">
<Setter Property="SnapsToDevicePixels" Value="true"/>
<Setter Property="OverridesDefaultStyle" Value="true"/>
<Setter Property="MinHeight" Value="23"/>
<Setter Property="MinWidth" Value="75"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border Name="Border" CornerRadius="2" BorderThickness="1"
Background="#C0C0C0"
BorderBrush="#404040">
<ContentPresenter Margin="2"
HorizontalAlignment="Center"
VerticalAlignment="Center"
RecognizesAccessKey="True"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsKeyboardFocused" Value="true">
<Setter TargetName="Border"
Property="BorderBrush" Value="#202020" />
</Trigger>
<Trigger Property="IsDefaulted" Value="true">
<Setter TargetName="Border"
Property="BorderBrush" Value="#202020" />
</Trigger>
<Trigger Property="IsMouseOver" Value="true">
<Setter TargetName="Border"
Property="Background" Value="#808080" />
</Trigger>
<Trigger Property="IsPressed" Value="true">
<Setter TargetName="Border"
Property="Background" Value="#E0E0E0" />
<Setter TargetName="Border"
Property="BorderBrush" Value="#606060" />
</Trigger>
<Trigger Property="IsEnabled" Value="false">
<Setter TargetName="Border"
Property="Background" Value="#EEEEEE" />
<Setter TargetName="Border"
Property="BorderBrush" Value="#AAAAAA" />
<Setter Property="Foreground" Value="#888888"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Notice that this template creates a button the simplest possible way: a border that contains the button content. It does not use another button embedded inside the template.
